Description

Technical Field

[0001] The invention relates to the technical field of quartz sand purification, and in particular to a device and method for removing impurities from inclusions in high-purity quartz sand. Background Art

[0002] Quartz stone is a non-metallic mineral whose main mineral component is silicon dioxide. Quartz sand is quartz particles processed by quartz stone through crushing, screening and other processes. Quartz sand, as an important industrial material, is widely used in semiconductors, photovoltaics, optics and other fields, and high-purity quartz sand is an indispensable key raw material in these high-end fields. With the rapid development of related industries, the requirements for the purity of quartz sand are increasing. In the process of quartz sand purification, the removal of inclusion impurities becomes a key link, which directly affects the quality and application performance of quartz sand.

In this invention, quartz sand falls into the combustion chamber, and the impurities are heated and agglomerated by the flame spraying device, and the quartz sand is blown to the middle of the filter plate by the wind force of the fan, and the vibration device vibrates, and the filtered quartz sand falls into the funnel, and the device is discharged through the discharge port, and the impurity blocks are collected by the waste collection box to complete the impurity removal of quartz sand.

DETAILED DESCRIPTION

[0024] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] Example 1: A high-purity quartz sand inclusion impurity removal device, such as Figure 1-Figure 4As shown in the figure, it includes a feeding cylinder 1, a support 101, a flame sprayer 102, a flame spray pipe 103, a cleaning cylinder 104, a bottom plate 105, a fixing frame 2, a protective shell 201 and a snap ring 203. A support 101 is fixedly connected inside the feeding cylinder 1. A flame sprayer 102 is rotatably connected to the support 101. The flame sprayer 102 is a prior art. The upper end of the flame sprayer 102 is connected to a device providing fuel from the outside through a rotatably connected pipeline to continuously heat the quartz sand. Three circumferentially distributed flame spray pipes 103 are fixedly connected to the flame sprayer 102. A plurality of circumferentially distributed flame spray holes are opened on the side wall of the flame spray pipe 103. The flame sprayer 102 can spray the flame through the flame spray holes on the flame spray pipe 103 to burn and remove impurities from the quartz sand. And a plurality of protrusions are provided on the side wall of the flame spray pipe 103 to facilitate better stirring of the quartz sand. A cleaning cylinder 104 is sleeved on the outer wall of the feeding cylinder 1. Both the feeding cylinder 1 and the cleaning cylinder 104 are hollow annular structures. From Figure 1 it can be seen that a fixing frame 2 is fixedly connected to the feeding cylinder 1. A protective shell 201 is fixedly connected to the middle of the fixing frame 2. Combining Figure 3 and Figure 4 it can be seen that a snap ring 203 is provided under the protective shell 201. A bottom plate 105 is fixedly connected to the snap ring 203. The outer diameter of the bottom plate 105 is the same as the inner diameter of the cleaning cylinder 104. The bottom plate 105 and the cleaning cylinder 104 form a cleaning chamber for accommodating the quartz sand. The flame spray pipe 103 is located in the cleaning chamber. An outlet hole 8 for discharging the quartz sand is provided between the snap ring 203 and the bottom plate 105. The cleaning cylinder 104 can be lifted and lowered to discharge the cleaned quartz sand through the outlet hole 8. The protective shell 201 is sleeved outside the cleaning cylinder 104 to prevent the quartz sand from scattering during the discharging process.

[0026] As Figure 1-Figure 4 shown, it further includes a separation mechanism for facilitating the separate collection of the quartz sand and impurities. The separation mechanism is located under the snap ring 203. The separation mechanism includes an output box 6, an output pipe 601, a base 602, a drainage plate 603 and a flipping assembly. From Figure 3 it can be seen that a plurality of through holes for discharging impurities downward are arranged in an array on the bottom plate 105. From Figure 1 it can be seen that an output box 6 and a base 602 are fixedly connected to the lower side of the fixing frame 2. The base 602 is located below the output box 6, and the base 602 is used to be placed on the ground to support the entire device. The output box 6 is located below the snap ring 203. From Figure 4It can be seen that the upper side of the output box 6 is funnel-shaped. The output box 6 is used to receive impurities and quartz sand discharged from the impurity removal barrel 104. Two output pipes 601 are fixedly connected to the lower end of the output box 6, one of which is used to output quartz sand, and the other is used to output impurities. A guide plate 603 is rotatably connected in the output box 6, and the guide plate 603 is used to guide quartz sand and impurities. A flip assembly is connected to the impurity removal barrel 104, and the flip assembly can automatically adjust the inclination angle of the guide plate 603 according to the discharge status of quartz sand and impurities.

[0027] like Figure 1 and Figure 2 As shown, the flip assembly includes a flip gear 604, a flip rack 605 and a torsion spring 606. The flip gear 604 is fixedly connected to the rotating shaft of the guide plate 603, and the torsion spring 606 is sleeved on the rotating shaft of the guide plate 603. One end of the torsion spring 606 is fixedly connected to the rotating shaft of the guide plate 603, and the other end of the torsion spring 606 is fixedly connected to the side wall of the output box 6. The flip rack 605 is fixedly connected to the debris removing drum 104 through a support rod. The flip rack 605 can engage with the flip gear 604 during the lifting and lowering process of the debris removing drum 104.

[0028] Pour the quartz sand that needs to be cleaned into the cleaning cylinder 104, then start the flamethrower 102, the flamethrower tube 103 will spray the flame onto the quartz sand in the cleaning cylinder 104, then control the flamethrower 102 to rotate, the flamethrower 102 will drive the flamethrower tube 103 to rotate synchronously, stir the quartz sand through the flamethrower tube 103, so that the flame can evenly contact the quartz sand, improve the quality of cleaning, and through the stirring and heating method, some impurities can be separated from the quartz sand in the form of gas or solid, such as sulfide impurities in the quartz sand will undergo oxidation reaction, sulfide impurities such as pyrite, pyrite reacts with oxygen in the air at high temperature to generate dioxygen Solid products such as sulfur dioxide gas and iron oxide; solid impurities will fall downward into the output box 6 through the through holes on the bottom plate 105, and will be discharged from one of the output pipes 601 under the action of the guide plate 603. After the impurity removal is completed, the impurity removal cylinder 104 is controlled to move upward, and the protective shell 201 can guide the quartz sand so that the quartz sand can only flow downward into the output box 6 through the discharge hole 8. When the impurity removal cylinder 104 moves upward, the guide plate 603 will be driven to rotate through the flip gear 604 and the flip rack 605, so that the quartz sand can be discharged from the other output pipe 601 under the action of the guide plate 603, which is convenient for collecting impurities and quartz sand separately.

[0029] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, it further includes a dual-drive mechanism for improving the impurity removal and discharge efficiency. The dual-drive mechanism is connected to the snap ring 203. The dual-drive mechanism includes a large gear ring 202, a motor 204, a shaft rod 205, a large gear 206, and a commutation component. Combining Figure 3 and Figure 4 it can be seen that the large gear ring 202 is rotatably connected to the outer wall of the protective shell 201. The lower side of the large gear ring 202 passes through the snap ring 203 and is axially slidably connected thereto. From Figure 1 it can be seen that a motor 204 is fixedly connected to the side wall of the output box 6 through a support plate. A shaft rod 205 is fixedly connected to the output shaft of the motor 204. A large gear 206 is fixedly connected to the shaft rod 205. Both the large gear 206 and the large gear ring 202 are bevel gears, and the large gear 206 meshes with the large gear ring 202. A commutation component is connected to the bottom plate 105. When the bottom plate 105 rotates, it will drive the flame spraying pipe 103 to rotate in the reverse direction through the commutation component.

[0030] As Figure 3 , Figure 4 and Figure 6 shown, the commutation component includes a small gear ring 3, a sliding sleeve 301, a small gear 302, and a moving gear 303. A small gear ring 3 is fixedly connected to the lower end of the flame spraying pipe 103. The lower end of the small gear ring 3 is rotatably connected to a sliding sleeve 301. The sliding sleeve 301 cannot move axially away from the small gear ring 3. The sliding sleeve 301 is axially slidably connected to the center position of the bottom plate 105. A small gear 302 is fixedly connected to the upper end of the sliding sleeve 301. Three moving gears 303 distributed in a circumferential manner are rotatably connected to the lower end of the flame spraying pipe 103. One side of the moving gear 303 meshes with the small gear 302, and the other side of the moving gear 303 meshes with the small gear ring 3.

[0031] As Figure 2 shown, it further includes a convex block 7, a convex rod 701, and a fourth spring 702 for further improving the discharge efficiency. A fourth spring 702 is sleeved on the guide rod where the snap ring 203 and the large gear ring 202 are slidably connected. The fourth spring 702 is used to push the snap ring 203 to reset upward. A convex block 7 is fixedly connected to the top end of the snap ring 203. A convex rod 701 is fixedly connected to the side wall of the protective shell 201. The convex rod 701 is used to squeeze the convex block 7 downward to drive the bottom plate 105 to vibrate.

[0032] With the side where the motor 204 is located as the front, after pouring quartz sand into the impurity removal barrel 104, the motor 204 is started to make the shaft rod 205 rotate forward, and the shaft rod 205 will drive the snap ring 203 and the bottom plate 105 to rotate forward through the large gear 206 and the large gear ring 202. During this process, the protruding rod 701 will intermittently squeeze the protrusion 7 downward, and the fourth spring 702 will push the snap ring 203 to reset upward, so that the snap ring 203 and the bottom plate 105 will shake rapidly during the rotation process, thereby improving the discharge efficiency of impurities; during the forward rotation of the bottom plate 105, the flamethrower 102 will be driven to reverse through the sliding sleeve 301, the small gear 302, the moving gear 303 and the small gear ring 3. The relative rotation of the flamethrower 102 and the bottom plate 105 can not only improve the stirring effect, but also further improve the discharge efficiency of impurities, and the reversing component is a variable speed structure, so that the flamethrower 103 can rotate slowly.

[0033] Embodiment 3: Based on embodiment 2, Figure 1 and Figure 5 As shown, it also includes a discharge mechanism for controlling the discharge of quartz sand, which is connected to the shaft 205. The discharge mechanism includes a one-way sleeve 4, a convex disc 401, a first spring 402, a retaining ring 403, a guide plate 404, a stopper 405, a second spring 406 and an unlocking assembly. The shaft 205 is rotatably connected with the convex disc 401 through the one-way sleeve 4, and the convex disc 401 can slide axially on the one-way sleeve 4. The guide rod of the convex disc 401 is sleeved with a first spring 402. When the convex disc 401 slides in a direction away from the large gear 206, the first spring 402 will be compressed. A stopper is fixedly connected to the side of the convex disc 401 away from the large gear 206. Ring 403, a guide plate 404 is fixedly connected to the debris removing barrel 104, and a stopper 405 is slidably connected to the guide plate 404 in the horizontal direction. A second spring 406 is sleeved on the guide rod of the stopper 405. When the stopper 405 slides in the direction away from the stopper ring 403, the second spring 406 is compressed. During the rotation of the cam 401, the debris removing barrel 104 is lifted up through the stopper 405 and the guide plate 404, and the stopper ring 403 prevents the debris removing barrel 104 from descending by resisting the stopper 405. An unlocking assembly is connected to the stopper ring 403, and the unlocking assembly is used to drive the stopper 405 and the stopper ring 403 to disengage from contact so as to facilitate the debris removing barrel 104 to reset downward.

[0034] like Figure 4 and Figure 5As shown, the unlocking assembly includes an arc block 5, a push block 501 and a rotation limiting block 504. The arc block 5 is fixedly connected to the end of the convex disc 401 away from the retaining ring 403. A plurality of circumferentially distributed push blocks 501 are fixedly connected to the lower end of the retaining ring 203. The push blocks 501 are used to squeeze the arc block 5 to disengage the retaining ring 403 and the stop block 405. The rotation limiting block 504 is fixedly connected to the retaining ring 403. The overall structure of the rotation limiting block 504 is trapezoidal. The stop block 405 prevents the one-way sleeve 4 from rotating forward through the rotation limiting block 504, so that the arc block 5 and the push block 501 can be squeezed and matched.

[0035] like Figure 1 As shown, it also includes guide rods 502 and third springs 503. Three guide rods 502 are fixedly connected to the protective shell 201. The debris removal barrel 104 is axially slidably connected to the three guide rods 502. The third springs 503 are sleeved on the guide rods 502, and the third springs 503 are located above the debris removal barrel 104.

[0036] When the impurity removal barrel 104 needs to move upward to discharge the quartz sand, the control motor 204 drives the shaft rod 205 to reverse, and the shaft rod 205 will drive the cam 401 to reverse synchronously through the one-way shaft sleeve 4. During the rotation of the cam 401, the guide plate 404 will be pushed upward, and the stopper 405 will gradually move to the angle position between the cam 401 and the stop ring 403. Since the side of the stopper 405 protruding from the guide plate 404 is provided with an inclined surface, the inclined surface contacts the inner side surface of the stop ring 403, so the stopper 403 will squeeze the stopper 405 in the direction of the guide plate 404, and the second spring 406 will be compressed. When the stopper 405 withdraws from the inner side of the stopper ring 403, the second spring 406 will push the stopper 405 to reset, so that the stopper 405 moves to the outside of the stopper ring 403, and during the continued reversal of the shaft rod 205, the stopper ring 403 prevents the guide plate 404 from descending through the stopper 405, thereby 104 remains in an upward state so that the bottom plate 105 can quickly throw the quartz sand to the position of the discharge hole 8 by centrifugal force; when the quartz sand on the bottom plate 105 is completely discharged, the motor 204 is controlled to stop rotating, and then the motor 204 is controlled to drive the shaft rod 205 to rotate forward. When the shaft rod 205 rotates forward, no rotational force will be applied to the convex disc 401 through the one-way sleeve 4, and the block 405 will prevent the retaining ring 403 from rotating forward through the rotation limit block 504, thereby preventing the convex disc 401 from rotating forward. However, at this time, the retaining ring 203 will rotate forward, and the retaining ring 203 will squeeze the arc block 5 through the push block 501, so the convex disc 401 will drive the retaining ring 403 to slide in the direction away from the retaining ring 203, and the first spring 402 will be compressed, so that the retaining ring 403 is moved away from the bottom of the block 405, so that the impurity removal barrel 104 can be reset downward under the push of the third spring 503, and then the first spring 402 pushes the convex disc 401 and the retaining ring 403 to reset.

[0037] A method for removing impurities from high-purity quartz sand inclusions, comprising the following steps: The first step is to add the quartz sand that needs to be cleaned into the cleaning cylinder 104 through the feeding cylinder 1; The second step is to start the flamethrower 102 to spray fire through the flamethrower tube 103 to stir and heat the quartz sand; In the third step, the solid impurities removed from the quartz sand during the stirring and heating process will pass through the bottom plate 105 and fall downward; The fourth step is to control the impurity removal cylinder 104 to move upward to discharge the impurity-removed quartz sand from the bottom plate 105.
